SELF-ADJUSTING CASING FOR ROLLER-BEARINGS.

Specification of Letters Patent.

Patented May it, rain.

Application filed March 26, 1909. Serial No. 485,971.

T 0 all whom it ma concern: Be it known that-I, CHARLES S. Leone wow, a citizen of thoUnited States, residing at "383.) Market street, Newark, county of Essex, and State of New Jersey, have 1n-' vented certain new and useful Improvements in Self-Adjusting Casingsfor Roller-Bearings, fully described and represented 1n the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to roller hearings in which two sets of tapering rolls are fitted to a double conical hub so that their sloping outer surfaces may be embraced by two opposed conical seats which can be suitably adjusted toward one another to compensate for wear and take up lost motionof the rolls.

.In the present invention, the seats are formed upon separate rings and made with spherical exterior and fitted to a spherical casing so that thebearing is wholly self-adjusting to various positions .of the shaft within a certain range.

The exterior of the casing is preferably made cylindrical so that such bearings may be fitted interchangeably into a cylindrical socket of a glven size. This enables the bearings to be made in standard sizes as regular articles of manufacture for supplying manufacturers of automobiles and other machines, and greatly facilitates the renewal of the parts when necessary. j

The invention will be understood by reference to the annexed drawing, in which Figure 1 is across section on line 4:4 in Fig. 3; Fig. 2 is an elevation of the parts with the casing removed; Fig. 3 is an end view of one-half of the casing with the rolls therein and the hub in section on line 3-3 in Fig. 1; and- Fig. '4 is an elevation of the hub shown in Fig. 1.

The hub is shown with double conical seats h adapted to be secured upon a shaft or axle in any suitable manner, and two sets of tapering rolls 2' are shown fitted to such seats with their larger ends in contact and held in place by a cage. The cage is formed with arms j, marginal rings is and with centraljoint-rings Z. Therings 7c rotate upon cylindrical seats m upon the ends of the hub,

and the joint-rings Z are secured together by rivets, after applying them to the opposite ends-of the hub. The rolls can then be applied to the spaces between the arms Tw bearing-rings n areshown fitted to embrace the outer sides of the two sets of rolls and formed with sloping seats 0 t0 fit the inclination of the rolls. The exteriors of the two bearing-rings n are curved spherically, being concentric with the center of the bearingindicated by the dotted'circle s in Figs 1 and 3. The casing is divided transversely into twoparts p and 5 connected by thread ed flanges r, and the parts are formed at 0pposite sides of its transverse diameter with concentric spherical seats 25 which form a spherical joint with the bearing-rings; and can be adjusted snugly to the same by screwing together the threaded collars '1. The rings n are separated by an inter-space n in which the joint-flanges Z of the cage can revolve, room for such space resulting from the flaring position of the adjacent ends of the rolls 2'. The contiguous corners of the rolls are beveled to run against one another.- The outer flange #r is provided, as shown in Fig. 3, with a notch v, and a series of ta pholes u is formed in the inner flange so that a screw can be inserted through the notch into any of the said holes and the head of the screw be wholly inclosed in the notch.

. The screw and the series of tap-holes furnish a means of locking the parts of the casing together when suitably adjusted and without any projection from the exterior cylindrical body of the casing, which would prevent it from fitting into a cylindrical socket of corresponding size. This con struction also permits the parts to be adjusted to compensate for wear and thus avoids lost motion in the hearing.

The hub is highest at the middle, while the seats 0 in the rings 11 and the spherical seats 2- in thecasing taper toward the ends of the hearing, which prevents the hub from ."hifting cndwisc in either direction within the casing, and the bearing thus resists end thrust as well as the lateral strain of the load. The two parts-of the casing are shown provided at their outer ends with flanges g which extend to the hub and serve as dustguards, and also as oil-retainers to keep oil in the lower part of the bearing.

The use of separate rings 1). with tapering seats 0 within the same to embrace the rolls; and a spherical exterior, not only makesthe parts adjustable to-the rolls but self-adjusting within the casing to various an ular 0'; positions of the shaft within limits. It will 9 be observed that the n are not coupled together in any manner but are held in the carry the rings with them. The engagement of the rings with the spherical bore resists the outward thrust exerted upon the rings and thus holds them in. their working position.

Ylrlaving" thus set forth the nature of the invention what is claimed herein is:

1. As 'a new article of manufacture, a

whit-contained and self-adjusting rollerbearing having a hub with the double conical seats h and two sets of tapering rolls i seen to such seatswith their larger ends adjacent, a casing having a spherical bore, and two rings at fitted to the said bore at opposite sides of its diameter and provided with tapering seats 0 embracing the outer side's of the two sets of rolls. a

2. As a new article of manufacture, a

, self-contained and self adjusting rollerhearing having a hub with the double conical seats h and two sets of tapering rolls z fitted tosuch seats, a cage ifitted to revolve about the hub with the rolls to guide the same, a; casing having a spherical bore, and two rings n fitted to the said bore atopposite sides or its transverse diameter with inter-space abetween the'rings for the periphery of the cage, the casing being divided and provided with means -for adjusting toward one another the spherical surfaces which bear upon the rin s n.

3. As a new article oi manufacture, a roller-bearing having a hub with double conical seats 7: and two sets'oi tapering rolls fitted to such seats, a casing provided with a spherical bore and-two rings n fitted to the said bore at opposite sides of its diameter and 'rovided with tapering seats 0 embracing' t e outer sides or the W0 sets of rolls,

the casing being dividedand the parts con-.

nccted by screw-threads, the outer part having the notch 12 therein and the inner part having a series of tap-holes to coincide separately with such notch, and a screw adapted to engage the notch and any one of the said holes and wholly inclosed by such notch, whereby the arts of the casing may be adjusted and its cylindrical exterior fitted directly toa cylindrical socket.

l. As a new article of manufacture, a

- self-contained and self-adjusting rollerbearing having a hub with the double conical seats h and two sets of tapering rolls 2' fitted to such seats with their larger ends adjacent, a cylindrical casing having a spherical bore, and two rings n fitted to the said bore at opposite sides of its diameter and provided with tapering seats 0 fitted respectively to the outer sides of the two sets of rolls, the casing being divided and the parts connected by screw-threads, the outer art 1" having the notch 01 therein and the inner part having a series of tap-holes, and a screw adapted to engage the notch and any one of the said holes and wholly inclosed by such notch.

5. A self-contained and self-adjusting roller-bearing having a cylindrical periphery adapted to removably fit'a'cylindrical socket, t e bearing having a hub with the double conical seats h and two sets of tapering rolls fitted to such seats, ,two rings a with taperi bore embracing the outsides ofthe rolls and having their exteriors curved concentrically and spherically, and the cylindrical casing of the bearing having a spherical bore arranged and operated to.

hold the tapering rings in their working position, and 'dividedtransversely in two parts for application to the rings, and the casing having at both ends of the rolls integral dust-guards extended toward the hub, the two parts of the casing being connected adjustably together. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
